Description

Technical Field

[0001] This utility model relates to the connection structure between the door body and the shell. Background Technology

[0002] See Figure 1-4 As shown, the existing door body 1 and the front panel 2 of the shell are connected by hinges 33. Due to the structural limitations of hinge 3, the hinge 3 is relatively long, restricting its installation to the edges near the left and right sides of the door body 1. A large installation space needs to be reserved on the back of the door body 1. This hinge 3 is a long strip with a single buckle, resulting in relatively low overall strength and poor door opening and closing performance. The length of hinge 3 also limits the viewing area and size of the door body 1. Utility Model Content

[0003] The purpose of this invention is to provide a door and shell connection structure with a hinge installation position that is more central compared to existing technologies.

[0004] The purpose of this utility model is achieved as follows.

[0005] A door and housing connection structure includes a door body, a front panel of the housing, and a hinge. The hinge includes a movable seat, a fixed seat, and a tension spring. The bottom of the movable seat and the inner end of the fixed seat are rotatably connected by a pivot. A first fixed post is provided at the top of the bottom of the movable seat away from the fixed seat, and a second fixed post is provided at the position of the movable seat near the pivot. One end of the tension spring hooks the first fixed post, and the other end of the tension spring hooks the second fixed post. The tension of the tension spring causes the top of the movable seat to move towards the outer end of the fixed seat. The movable seat is fixed to the bottom center position of the door body by a connector. The front panel has a mounting hole, and the outer end of the fixed seat has a hook. The fixed seat is horizontally set, and the hook passes through the mounting hole and the hook on the back of the front panel.

[0006] Furthermore, the fixing seat has a U-shaped cross-section, and two parallel hooks extend from the outer end of the fixing seat. This improves structural strength.

[0007] Furthermore, the fixed seat is rotatably mounted inside the movable seat. The fixed seat has a stepped buckle in the middle. The movable seat has a positioning post and a torsion spring inside. The two ends of the positioning post are movably mounted in the limiting movable grooves on both sides of the movable seat. The limiting movable grooves are set along the height of the movable seat. One end of the torsion spring abuts against the movable seat, and the other end of the torsion spring is connected and fixed to the positioning post. The elastic force of the torsion spring causes the positioning post to move towards the bottom end of the fixed seat in the limiting movable groove until the positioning post and the bottom end of the limiting movable groove abut against each other.

[0008] Furthermore, a first limiting part is provided on the inner side of the movable seat, and a second limiting part is provided on the outer side of the fixed seat. The top of the movable seat rotates away from the movable seat until the first limiting part and the second limiting part come into contact and stop. The first limiting part and the second limiting part cooperate to limit the maximum opening angle of the hinge.

[0009] Compared with existing technologies, this invention features a smaller hinge size, which is installed on the bottom surface of the door body in a slightly centered position, making installation convenient and easy. The overall hinge structure is simple and reasonable, and it incorporates a U-shaped design, resulting in good strength and smooth door opening and closing. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Example 1, see Figure 5-9 As shown, a door and housing connection structure includes a door body 1, a front panel 2 of the housing, and a hinge 3.

[0021] The hinge 3 includes a movable seat 4, a fixed seat 5, a tension spring 6, a pivot 7, a first fixed post 8, a second fixed post 9, a positioning post 10, and a torsion spring 11. Both the movable seat 4 and the fixed seat 5 have U-shaped cross-sections. The bottom of the movable seat 4 and the inner end of the fixed seat 5 are rotatably connected via the pivot 7, meaning the inner end of the fixed seat 5 is rotatably positioned within the movable seat 4. The first fixed post 8 is located at the top bottom of the movable seat 4, away from the fixed seat 5. The second fixed post 9 is located on the movable seat 4 near the pivot 7. One end of the tension spring 6 hooks onto the first fixed post 8, and the other end hooks onto the second fixed post 9. The tension of the tension spring 6 causes the top of the movable seat 4 to move towards the outer end of the fixed seat 5. The fixed seat 5 has a stepped latch 50 in the middle. The movable seat 4 has limiting grooves 40 on both sides, which are set along the height of the movable seat 4. The two ends of the positioning post 10 are movably disposed in the limiting grooves 40. One end of the torsion spring 11 abuts against the movable seat 4, and the other end of the torsion spring 11 is connected and fixed to the positioning post 10. The elastic force of the torsion spring 11 causes the positioning post 10 to move towards the bottom end of the movable seat 4 within the limiting groove 40 until the positioning post 10 and the limiting groove 40 abut against the bottom end of the movable seat 4. The two outer sides of the movable seat 4 are provided with ears 41, and the ears 41 are provided with screw holes 42. Two parallel hooks 51 extend from the outer end of the fixed seat 5. The first fixed post 8, the second fixed post 9 and the positioning post 10 of the pivot 7 are arranged in parallel.

[0022] The movable seat 4 has a first limiting part 43 on its inner side and a second limiting part 52 on its outer side. The top of the movable seat 4 rotates away from the movable seat 4 until the first limiting part 43 and the second limiting part 52 come into contact and stop. The first limiting part 43 and the second limiting part 52 cooperate to limit the maximum opening angle of the hinge 3.

[0023] The movable seat 4 is fixed to the bottom center of the door body 1 by a connector (such as a screw) passing through the screw hole 42. The bottom center of the front plate 2 is provided with a mounting hole 20. The fixed seat 5 is horizontally set, and the hook 51 passes through the mounting hole 20 and the hook on the back of the front plate 2.

[0024] During the door closing process, the positioning post 10 needs to pass over the stepped latch 50. The positioning post 10 moves towards the top end of the fixed seat 5 within the limiting movable groove 40 and compresses the torsion spring 11. The positioning post 10 moves to pass over the stepped latch 50. After the positioning post 10 passes over the stepped latch 50, the elastic force of the torsion spring 11 causes the positioning post 10 and the side of the stepped latch 50 to abut against each other. At the same time, the tension spring 6 pulls the top of the movable seat 4 to abut against the fixed seat 5 and stop, thus keeping the door in contact with the front panel 2.

[0025] The terms used in this utility model, such as "first," "second," etc., do not indicate any order, quantity, or importance, but are only used for distinction.

[0026] In this invention, terms such as "a" or "an" are used to indicate not a limitation on the quantity, but rather to indicate the existence of at least one of the mentioned objects.

[0027] In this utility model, terms indicating direction or location such as front end, rear end, top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, below, etc., are used to indicate relative positions rather than absolute positions.

[0028] Terms used in this invention, such as "approximately," "generally," "approximately," and "similar," are limiting terms used to indicate features that exist but allow for certain deviations. The amount of deviation allowed may vary depending on the specific context.
